Hello,
We have been seeing a similar problem when we tried to change a top block by
stopping it and then creating a new top block.
First it looked like the problem was related to the synchronization of uhd

Hi,
I'm using the UCLA ZIGBEE PHY implementation by Thomas Schmid:
Does anyone have an idea, how I could build a connection/communication
between the files/functions in the files:
- ucla_clock_recovery_ff_mm.cc
- ucla_ieee802_15_4_packet_sink.cc
such that a variable within clock_recovery is

Tom,
Thank you for your help first of all.
I actually need the file_source to be replayed, meaning not just repeated
over and over, after the frequency is changed. I also have to make sure
that the file_source is played just once for each frequency change. Would
that still not require a stop?

Hi,
I'm using UCLA ZigBee Phy by thomas schmid:
Now i try to ignore every second entry of the variable d_shift_reg in
the file ucla_ieee802_15_4_packet_sink.cc.
Does anyone have an idea how i could implement something like that?
best regards and thank you for any answers,

OK. My guess is the timeout requirement for communicating with the
Firefly has changed with new firmware, and I'm not waiting long enough
between commands. I'll poke at it today.

Hello everyone,
I am currently working with multiple receivers of USRP N210s. I would
like to correlate the received signal of multiple receivers and
therefore require them to start sampling at the same time. Is there a
good way to implement that?
Regarding to that issue I was curious to see samp
